Chandalen - Thanks for your input. I'm learning about all the software options from the many posters here. Very cool. Thanks everyone!!
pnichols - We actually upgraded to AGM batteries on our trailer in April and had them for all our years on our boat as well, so I discuss them at length in the first post in the series on battery charging (you probably didn't check out that post since you've been around that block already... no problem!). I really appreciate all your detailed notes on AGMs and will add the tidbits I missed! Thanks for reading my other goodies in the past too!!
